Max Colombié Posted March 4, 2018 Share Posted March 4, 2018 Hi everyone, I'm looking to setup next week some heated grips and I would like your opinion for the wiring. Where do you think I should wire the system? I was thinking to use the hot wire from my turn signal and connect the negativ to the chassis. However I'm afraid that the current would be too high (almost 3A) and fry the wires. (I use leds turn signals not bulbs tho). I was also thinking about maybe using a relay to have the + and - coming directly from the battery. But it may be overkill. What are your thoughts? Thanks !

Global Moderator mjh937 Posted March 4, 2018 Global Moderator Share Posted March 4, 2018 I have the Yamaha heated grips and they connect directly to the battery. I would follow the instructions with the grips you get. They should automatically shut off when the bike is not running and there is any voltage drop. The turn signal wire ui definitely too small for that amperage draw. Link to comment Share on other sites More sharing options...

Maybe I can upgrade my headlamp for a LED? The current reduction might be enough. I'll do some research Link to comment Share on other sites More sharing options...
Max Colombié Posted March 4, 2018 Author Share Posted March 4, 2018 The led headlight seems to draw as much current. I don't have any option left than going for the relay I guess. Link to comment Share on other sites More sharing options...

rick Posted March 4, 2018 Share Posted March 4, 2018 Those grips only draw 3A total? 36W between the 2 grips, doesn't seem like much heat. A relay is not only the safest way to deal with it, but also allows you to use properly large wires so you have no loses between the voltage supply and the hungry grips. Don't forget a fuse, preferably close to the battery You can use the accessory plug to switch the relay so the grips can't be left on. Link to comment Share on other sites More sharing options...

Xom Posted March 5, 2018 Share Posted March 5, 2018 Sorry to hi-jack slightly, but very relevant. I noticed that Yamaha sell a connector to connect heated grips directly to the Aux plug. I also note that the fuse for this is 2A which I would have thought would have ruled out being able to use it for heated grips. However, looking at the instructions for the OEM Yamaha heated grips, it suggests that on full power in the these use just 22W which is just slightly over 1.8A. Does this not seem very very little for what most people say is an effective heater? Link to comment Share on other sites More sharing options...

Premium Member norcal616 Posted March 5, 2018 Premium Member Share Posted March 5, 2018 I have had better luck using gloves with thin palm material so I can feel the heat...using winter gloves are thick and wont transfer heat to your hands... same thing goes for heated gear, use it as close to your body as possible preferably the first layer after putting on your fancy underwoos... 2015 fz-07- Hordpower Edition...2015 fj-09- 120whp- Graves Exhaust w/Woolich Race Kit- tuned by 2WDW Link to comment Share on other sites More sharing options...

What type of instruction manual comes with a water pump? Headlight bulb? Standard replacement grip? If they're going to go to the trouble to print out instructions they might as well do a good job of it, but many things don't come with instructions at all, for a reason.

AlbatrossCafe Posted March 5, 2018 Share Posted March 5, 2018 Wire it to the battery. Use a relay or have a sticky note reminding you to turn it off. My grips have a 15A fuse inline coming off the battery. There is no hot wire for anything else in the dash that you can safely tap into to give you that much power.
